Fizzy Yellowtail

#a1bc25
Notes

Fizzy Yellowtail (#A1BC25) is a true yellow with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (71°, 67%, 44%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fizzy
adjective

Imitative-onomatopoeic origin — adjectival suffix -y, evoking the sound of carbonation. As a color modifier, fizzy implies a saturated-and-effervescent-and-bubbly quality, the bright color of Champagne-and-Prosecco effervescent-wine carbonation-bubble-light reflection. Sits at the bright-and-effervescent end of the grid, parallel to bubbly and sparkling in usage.

Yellowtail
noun

Seriola lalandi, the Pacific yellowtail amberjack — a sport fish prized in Japanese sushi cuisine as hamachi. The color refers to the yellow stripe along the lateral line: a saturated, slightly cool yellow with the matte finish of carotenoid-pigmented fish skin. Cooler than goldfinch.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
